Off-Axis parabolic first surface metal mirrors

Share this on social media:

Edmund Optics has introduced new off-axis parabolic first surface metal mirrors. Intended for use in broadband visible and IR applications, each mirror is interferomically tested and features a surface roughness down to 50Å RMS. Off-axis parabolic mirrors have no spherical aberration and are free of chromatic aberration over a broadband range because they are not wavelength dependent. These mirrors are ideal for use in instrumentation and laser systems, including Schlieren, MTF, IR, FLIR and FTIR systems.

The new mirrors feature a solid metal design and use no adhesives to achieve excellent thermal conductivity. They also have a focal point which is not in line with the optical axis, allowing users to incorporate various components into the system and optimise workspace. 

The mirrors are available with a reflected focal length range from 12.7mm to 516mm in 15°, 30°, 45°, 60° or 90° off-axis options. In-house design, manufacturing, and coating capabilities are available for custom requests, including ellipsoid shaped metal mirrors.
